Introduction
Preliminary
Programmable Peripheral
PSD7XX Family
Field-Programmable Microcontroller Peripherals
with Supervisory Functions
Key Features
J
A simple, programmable interface to 8 or 16 bit microcontrollers using either multiplexed
or non-multiplexed busses. The bus interface logic directly decodes microcontroller
control signals. Microcontroller families supported include the Intel 8031, 80196,
80186, 80C251 and 80386EX; Motorola 68HC11, 68HC16, 68HC12 and 683XX; Philips
8031 and 8051XA; National 16000; Zilog Z80 and Z8; and Neuron 3150.
J
Three PLDs with 12 Output Micro
Cells and 24 Input Micro
Cells, 66 inputs and
132 product terms. The PSD7XX PLDs may be used to efficiently implement a variety
of logic functions including state machines and address decoders for internal and
external control. The PLD also provides seven external chip select outputs and
generates control for the WatchDog timer.
J
Embedded Input and Output Micro
Cells enable efficient implementation of user
defined system logic functions that require both microcontroller software and hardware
interaction.
The PSD7XX series is the first family of PSD Field Programmable Microcontroller
Peripherals that includes Supervisory Control Functions. PSD7XX devices are used to
rapidly implement a highly integrated embedded control system. PSD7XX devices integrate
many of the peripheral functions inherent in microcontroller based applications including:
EPROM, SRAM, programmable logic, reconfigurable I/O ports, programmable power
management, voltage monitor, and WatchDog timer. The PSD7XX family provides a
complete solution for microcontroller support and protection.
The PSD7XX family is developed around an innovative “microcontroller-macrocell” logic
architecture called the Micro
cell. The Micro
cell was specifically created to address the
unique requirements of embedded system designs. It allows direct connection between the
system address/data bus and the PSD registers which greatly simplifies communication
between the MCU and supporting devices.
In addition to the Micro
cell based PLD, the PSD7XX offers all of the Supervisory functions
needed to monitor embedded system performance. These functions include programmable
voltage monitor, WatchDog timer, reset pulse generator and an automatic battery backup of
the on-board SRAM. Since the Supervisory functions are fully programmable, the PSD7XX
offers the flexibility of using a standard, off the shelf product in a variety of designs under
different voltage, reset and clock frequency requirements.
